EMIL REYEB, OF SOUTH BEND, INDIANA rArEn FOLDING GUIDE Application filed December 31, 1930. Serial No. 505,725.

The invention relates to paper folding guides, and particularly to guides for the folding of druggists powder papers and the like, and has for its object to provide a device by means of which the folding of powder papers and the like may be guided to provide a folded paper of any desired dimenslon.

A further object is to provide a device of this character in which two upstanding spaced members having straight upper edges over which the ends of a paper may be folded are provided, and in which theposition of said members relative to each other is adjustable.

3 A further object is to provide a device of this character in which adjustably' spaced, parallel, upstanding plates, over which the ends of a paper may be folded, are provided, said plates being provided with means supporting them against inward deflection.

A further object is to provide a device of this character comprising upstanding members and a guide member, one of said plates being adjustably mounted on said guide member and provided with means frictionally engaging said guide member whereby its position relative to the other plate may be guided in predetermined manner, and its predetermined position maintained by said frictional means.

With the above and other objects in view, the invention resides in the combination and arrangement of parts as hereinafter set forth,

shown in the drawings, described and claimed, it being understood that changes in the precise embodiment of the invention may be made within the scope of what is claimed without departing from the spirit view of my device.-

- I have "therefore constructed a device,

- the inner dimensions of the box and do not properly fit therein, so that they must be again folded before theycan be inserted in the box all of which is inconvenient and entails a waste of time with possibility of loss of the contained powders and the like. It

is therefore the principal purpose of my device to provide a guide means by the use of which such papersmay be properly folded to fit within a box of any given size without the necessityof refolding, or of cramming into a box papers of a size larger than the inner dimension of the box. 7

which, referring tothe drawings, comprises a flat, horizontal'plate 2, preferably of sheet metal, forming a base or guide member, one end of said base 2 being downwardly bent at 4 to form a support by which that end of the base is positioned above the surface of the member on which it is mounted. At its other end the base terminates in a downwardly ex- V tending double return bent portion 6, also so forming a support therefor, which extends into a return bent portion 8 overlying the end of the base, and terminates in an upstanding plate 10 spaced from the end of the base; said base thus being positioned in horizontal spaced relation'above'the surface on whichit is mounted, for purposes to be hereinafter set forth. Intermediate the ends of the base isnrounted an adjustable member comprising an upstanding plate 12 which has a horizontally extending flange 1A formed atits'lower end'to overlay the base, the outer ends 16 of said flange 14 being inwardly return bent into frictional engagement with the under side of the base2 and clearing the surface. onwhich the device is mounted so that it is free to move longitudinally of the base 2. The plate 12'is positioned parallel to the plate 10 at all'times by the flanges 14: and 16 engaging the base 2 which thus 1 0 forms a guide for the adjustable member, and the upper edges of plates 10 and 12, which are straight, are always parallel.

Obviously in use the plate 12 is positioned with its outer face spaced from the outer face of plate 10 a distance less than the inner dimension of the box into which the folded papers are to be placed, and the papers are held across the upper edges of the plates and folded over said plates along the lines at which said plates engage the papers, as illustrated in dotted lines in Figure 2. The frictional engagement of the flanges 14 and 16 with base 2 holds the plate 12 in the desired position while the papers are being folded on the device; and said flanges also serve to support said plate against deflection upon the application of inwardly directed stress thereto incident to the folding operation. The portion Sfrom which the plate 10 extends, and the double return bent portion 6, prevent inward'deflection of'plate 10 under the same inward stress. Thus the device maintains its proper position after being set and is properly supported against the stresses applied thereto incident to its use. The supports 4 and 6 which space the base above its supporting surface permit shifting of the plate 12 on the base without engaging the supporting surface.

In Figure 4 I have illustrated a modified construction of my device in which a base plate 20 is employed. One end 22 of this base plate is downwardly bent to form a support, and the other end is downwardly bent at 24c and terminates in a return bent upstanding plate 26. Supporting flanges 28, preferably integrally formed with plate 26 are inwardly perpendicularly bent at each side of plate 26 with their lower edges engaging the base 20. An upstanding plate 30, parallel to plate 26, is mounted on base 20 intermediate the ends thereof and has a perpendicularly inwardly directed flange 32 overlying the base and terminating in inwardly directed return bent flanges 34L frictionally engaging the under side of the base. Supporting flanges 36 are perpendicularly inwardly bent from the sides of plate 30 with their lower edges engaging the flange 32. In this construction the flanges 32 and34: have the same frictional engagement with the base to hold the plate 30 in desired position as in the preferred construction; and in addition the supporting flanges 28 and 36 form positive meansfor supporting the upstanding plates against inward stresses applied thereto in the use of the device.

In Figure 5 is illustrated the manner in which powder papers 38 are generally packed in a box 40. In Figure 2 the manner in which a powder paper 38 is folded in the use of the device is illustrated in dotted lines.

The invention having been set forth, What is, claimed as new and useful is:

1. In a paper folding guide, a horizontal base plate, an upstanding plate extending from one end of said base plate, a second upstanding plate mounted on said base, a horizontal flange mounted on said base plate and extendingfrom the lower end of said second upstanding plate, and means carried by said flange engaging said base to permit directed sliding of said second plate on said base.

2. In a paper folding guide, a horizontal base plate, an upstanding plate fixedly carried by said base plate, and a shiftable upstanding'plate carried by said base, a horizontal flange carried by the lower end of said shiftable plate and mounted on sai base plate, and return bent flanges carried b said horizontal flange and frictionally engaging the under side of said base member.

3. In a paper folding guide, a base plate having portions thereof bent downwardly at its ends to form supports, an upstanding plate extending from one of said downwardly bent portions, a second upstanding plate, a hori-
